Jan. 1 7, c N UF ENGINE OILING DEVICE Filed Sept. 4, 1928 Patented Jan. 17, 1933 UNITED STATES LOUIS C. VANDERLIP, OF ELKHART, INDIANA ENGINE orLme DEVICE Application filed September 4, 1928. Serial No. 303,694.

My invention relates to internal combustion engines and particularly to the lubrlcation system therefor.

As is well known in the internal combustion engine art the maintenance of the efliciency ofthe engine lubrication system is of ivvitalri portance ansliitrh agr d a ly b developedto a highdegree by the use of filters, purifiers &c. Nevertheless it has not been possible to prevent the accumulation of water, gasoline, and other deleterious substances in the engine base or oil pan, nor to prevent certainwell known injurious consequences due to such accumulation of water,

and other deleterious matter, which collect at the bottom of the oil pool and are readily taken up by the oil pump which circulates the lubricant-to the engine bearings.

Thevprincipal object of this invention is 23 to provide a device which enables the oil pump to take the lubricating oil from the surface of the oil pool in the engine oil pan and thereby distribute the purer oilv to the en 'ne bearin s. nother ob]ect of the invention is to provide a device for inspiring or pumping lubricant from the surface of the engine base oil pool to insure lubricant distribution in winter when accumulated water in the engine base mi ht freeze and close the inlet-orifice of the oil suction conduit. Other objects may be mentioned and described herein.

The preferred embodiment of my inven-' tion is illustrated in the accompany drawing, wherein,

Figure 1 illustrates a sectional view in side elevation through the base of an internal combustion engine showing the application of my invention thereto;

Fig. 2 illustrates an enlarged sectional view of the oil suction-pipe and the floating hood therefor;

Fig. 3 is a view of the suction element alone; and i Fig. 4 is a section taken on line of Figure 2.

imilar numerals-of reference indicate like parts throughout the several views on the drawlng.

Referring to the details of the drawing the numeral. 1 indicates an internal combustion engine provided with the usual base oil pan 2 which is adapted to contain the pool of lubricating oil 3 for distribution to the engine bearings 4 4 by a pump 5 and a pump suction conduit 6, as is well known in the art. 1 I

The conduit 6 along the bottom of the oil pan interior and may be connected at its outer end with the tubular elbow fitting 7 by screw threads 8. .An upright tubular oil suction element 9 may be screwed into the elbow fitting 7 at 10, the element 9 having a suction bore 11 which may be closed at the top end thereof by the annular head 12, said bore 11 being placed in communication with the exterior of the element 9 by a plurality of lateral orifices 13" formed adjacent the head portion 12. The numeral 14 indicates a plurality of grooves formed in the exterior of the suction element 9 and extending longitudinally thereof and substantially coextensive therewith, but which may'terminate below the annular head 12 of said element, each of said grooves bein in communication with one of the inlet ori ces 13 adjacent the top end thereof.

Preferably, the upper end of the'suction element 9 projects above the surface of the oil pool 3 and is encompassed by the hollow cylindrical hood-like element 15 which is carried by the float element 16 and adapted to be moved axiall of said suction element by said float, which is buoyantly' sustained in the oil pool, as the surface of said oil pool is raised or lowered by any means or for any reason.

The hood 15 is preferably a cylindrical element provided with the chamber 18 into which the element 9 telescopes slidabl the chamber 18 bein closed at the top en and said hood being built rigidly into and centrally of the float 16, both of which elements maiy be made of suitable sheet. metal.

n operation it is obvious that the oil will be drawn upwardly along the grooves 14, the upper portions of said grooves being encomp'assed by the hood 15, and throu h inlet orifices 13 into the suction element 9, y pump suction, and thence through pipe 6 to the pump. Also, it will be evident that the grooves 14 are in permanent communication with the pool of lubricant beneath the surface thereof, and that the oil will enter said grooves adjacent the lower end of the hood 15 and the float bottom, the latter of which is disposed close to the surface of the oil pool. Inasmuch as water and gasoline, and other deleterious matter, accumulate on the bottom of the oil pan, it will be evident that the best grade of the lubricating oil is taken from the pool and pumped to the engine bearings and that the inlet orifices 13, being disposed high above the oil pan bottom, cannot be closed by freezing of water in the bottom of said pan.

Various immaterial modifications of my invention may be made withouta departure from the spirit of the invention, and therefore, I am unwilling to limit myself to the exact form, construction, arrangement and combination of parts herein illustrated and described or uses specified.
